GENERAL RELEASE SPECIFICATION
PRELIMINARY
2.1
COP
The COP time-out is prevented by writing a ‘0’ to bit 0 of address $3FF0. See SECTION 11
for detail.
2.2
ROM
For MC68HC05BD7, the user ROM consists of 11.75K bytes of ROM from $1000 through
$3EFF and 16 bytes of user vectors from $3FF0 through $3FFF. For MC68HC05BD2, the
user ROM consists of 5.75K bytes of ROM from $2800 through $3EFF and 16 bytes of user
vectors from $3FF0 through $3FFF. The Self-Check ROM is located from $3F00 through
$3FE0 and Self-Check vectors are located from $3FE0 through $3FEF.
2.3
EPROM
For MC68HC705BD7, the user EPROM consists of 11.5K bytes of EPROM from $1000
through $3DFF and 16 bytes of user vectors from $3FF0 through $3FFF. The Bootstrap
ROM is located from $0E00 through $0FDF and Bootstrap vectors are located from $3FE0
through $3FEF, at the same location as Self-Check vectors.
2.4
RAM
The user RAM consists of 384 bytes from $0030 to $01AF for HC05BD7/HC705BD7. User
RAM consists of 256 bytes from $30 to $12F for HC05BD2. The stack pointer can access
64 bytes of RAM from $00FF to $00C0. See Section 3.1.3, Stack Pointer (SP).
NOTE:
Using the stack area for data storage or temporary work locations requires
care to prevent it from being overwritten due to stacking from an interrupt
or subroutine call.
